Our XML data is stored in separate files, so the personnel can work individually on simple modules. The separate files are assembled to one master file to be processed further. Currently I am doing this within the IDE of the Oxygen XML Editor. To streamline the process, I would like to do it from command line without this IDE. How can I resolve the the XInclude statements from command line with Saxon HE (if this is possible)?
I tried a command like this:
java -jar saxon9he.jar -xi:on -s:main.xml -xsl:assemble.xslt -o:master.xml -t
and get the following error code:

Saxonica's documentation on the xi:on parameter says: "Apply XInclude processing to all input XML documents (including schema and stylesheet modules as well as source documents). This currently only works when documents are parsed using the Xerces parser, which is the default in JDK 1.5 and later." (https://www.saxonica.com/documentation9.5/using-xsl/commandline.html) -- not sure, what this means.

Based on our exchange of comments and the advice you got from the oXygen support it looks like using oXygen's patched version of Xerces (available at https://mvnrepository.com/artifact/com.oxygenxml/oxygen-patched-xerces/21.1.0.2) together with Saxon 9.9 HE should work to enable xpointer based XInclude from xml:id attributes:
java -cp 'oxygen-patched-xerces-21.1.0.2.jar;saxon9he.jar' net.sf.saxon.Transform -t -s:input.xml -xsl:sheet.xsl -xi:on
This is the command line I have used and tested in a Windows 10 Powershell window, depending on the platform and command line shell you might need different quote characters for the -cp argument and a different item separator between differents jar files listed there.
